7 Apr 2011 | Abstract: | Recently, Boyer et al. presented a novel semiquantum key distribution
protocol [M. Boyer, D. Kenigsberg, and T. Mor, Phys. Rev. Lett. 99, 140501
(2007)], in which quantum Alice shares a secret key with classical Bob. Li et
al. proposed two semiquantum secret sharing protocols [Q. Li, W. H. Chan, and
D. Y. Long, Phys. Rev. A 82, 022303 (2010)] by using maximally entangled
Greenberger-Horne-Zeilinger states. In this paper, we present a semiquantum
secret sharing protocol by using two-particle entangled states in which quantum
Alice shares a secret key with two classical parties, Bob and Charlie.
Classical Bob and Charlie are restricted to performing measurement in the
computational basis, preparing a particle in the computational basis, or
reflecting the particles. None of them can acquire the secret unless they
collaborate. We also show the protocol is secure against eavesdropping. | Source: | arXiv, 1104.1270 | Services: | Forum | Review | PDF | Favorites |
